I don't know what this is but lately i can hear this dripping sound from in side the lower part of body i can't feel anything but i can hear it and also when sitting on the toilet...do anyone know what this is?...before i realize the dripping sound a few days ago i was sitting on the chair and i had to get up because my butt started to hurt...could not sit down...pain was in between the cheeks i guess i sat for too long and something in the lower part felt pressured on i think....i mean im skinny so i don't know.
